Description

United States Patent 3,164,523 COMPOSITION FOR SKIN BEAUTIFICATION AND TREATMENT Charles For, Fair Lawn, Fred S. Morshauser, Pompton Plains, and Paul Than, Westfield, N431, assignors to Warner-Lambert Pharmaceutical Company, Morris Plains, N.J., a corporation of Delaware No Drawing. Filed Mar. 22, 1961, Ser. No. 97,440
4 Claims; (Cl. 167-90) This invention relates to cosmetic compositions useful for application to the skin and relates more particularly to a new and novel cosmetic composition applicable for use in the treatment of the skin which is not only easily used but which has improved properties when used and applied to the skin.
For many years various cosmetic beauty masque compositions have been used for skin cleansing, depilatory and astringent purposes. Such compositions are commonly applied to the skin and particularly the face and neck, and are allowed to remain there for various periods of time to obtain the desired results. Recently, beauty masques in the form of a tough elastic gel have been obtained by the addition to water of a gel forming composition comprising the combination of a water soluble salt of alginic acid and a calcium salt in powder form. After the components are mixed with water-the paste formed is applied to the skin and after a shorttime sets into a tough, elastic gel structure. The gel is formed as a result of the reaction of the alginic acid salt with the calcium ions derived from the calcium salt with the formation of calcium alginate. In the co-pending applicaposition which, when mixed with water and applied to the skin, forms a tough elastic alginate gel with high tensile strength and improved adhesision to the skin without lifting or cracking, even after prolonged periods of contact with the skin.
A further object of this invention is to provide a composition which may be mixed with water and applied to the skin to form an elastic alginate gel over the entire surface covered by the composition without forming any dry and powdery areas around the edges of the gel.
Other objects and the advantages of this invention will become apparent from the following detailed description.
We have now found'that by combining a gel forming composition comprising a water soluble salt of alginic acid and a partially soluble calcium salt with an inert nonaqueous liquid vehicle to form a paste, the paste composition obtained may then be easily and conveniently mixed with water and When the water-modified paste is applied to the skin a tough elastic gel is formed of high tensile strength, improved adhesion to the skin and substantially no evidence of lifting or cracking, which resists undue drying where thinly applied and thus avoids the formation of dry powdery areas around the edges. Depending upon the nature and quantity of the non-aqueous tion of Charles Fox et al. entitled Method of Treating forming composition. The liquid must, of course, be nonthe Skin and Composition Therefor, Ser. No. 84,520, filed January 24, 1961, and now abandoned, such a gel forming vehicle has been disclosed as a useful carrier for various cosmetic and therapeutic agents for the localized treatment of the skin.
Although such compositions are effective, they suffer certain disadvantages. Since the gel forming composition is in a solid finely-divided powder form it must bepackaged in sealed envelopes to avoid absorption of moisture.
cosmetic skin treating agents and onlyrequire the addition of water to the mixture before use.
The term inert as applied to the liquid vehicle employed means that the material must be entirely nonreactive with any of the constituents present in the gelaqueous since any water present would immediately initiate, formation of a gel. The inert liquid, should, however, be compatible with water; that is, it should either be water soluble or capableof being easily and uniformly Again, to produce the desired gel the contents of the cation of the aqueous paste or suspension formed on mixing the composition with water forms dry powdery areas;
at the edges of the area to which it has been applied andthese are somewhat difficult to remove from the skin after the treatment period. With some users these elastic alginate gels show a tendency to crack or lift away from the surface of the skin in certain areas, a phenomenon which diminishes the effectiveness of the compositionin' cosmetic or therapeuticskin treatment where an intimate contact of the treating agent with the skin is'essential.
dispersed in water. This degree of compatibility insures that upon the addition of the composition to water during normal use, a smooth and uniform suspension is rapidly obtained. Exemplary of water soluble inert liquids useful in forming the novel compositions of this inverttion are the various dihydroxy and trihydroxy' alcohols such as ethylene glycol, propylene glycol, hexylene glycol, glycerine and the like as well as glycol ethers such as polyoxyethylene glycol and the like. Exemplary ofthose inert liquids which are readily dispersible in water are such materials as ethoxylated fatty alcohols, for example ethoxylated lauryl alcohol, the polyglycol esters, for example polyethylene glycol laurate, polyethylene glycol palmitate and the like and polyethe'rssuch as nonylphenoxypolyoxyethylene. Also included within the scope of the term inert liquid, as used herein, are water dispersible liquid systems comprising a mixture of a Wetting agent,
for example ethoxylated lauryl alcohol, ethoxylated oleyl alcohol, ethoxylated lanolin fatty alcohols, polyethylene glycol monolaurate, polyethylene glycol monooleate, nonylphenoxypolyoxyethylene and the like and a hydrocarbon It is an object of the present invention to provide an alginate gel forming composition which is adapted to simple, clean and ready mixing with water prior to use.
Another object of this invention is to provide a cornoil, foriexample mineral oil, or a fatty acid ester. such as isopropyl stearate, isopropyl myristate and the like.
The gel forming components which are blended with i said inert liquid 'to yield the compositions ofourinvention constitute a mixture of a water soluble salt of alg'inic acid,
forexample alkali metal and ammonium alginates, and a ,phate, and thelike. composition comprising a salt of alginic acid, an acid partially soluble calcium salt, for example calcium salic- ;upon addition of the above described composition to Water, it is desirable that the composition contain a gel retarding agent in addition to the alginic acid and calcium salts. Such an agent acts to delay the rate of formation of free calcium ions in the suspension and allows the user 1 ample time to add the water and then to mix the composition thoroughly in order to obtain the desired smooth and uniform suspension of the components in the now aqueous vehicle before gel formation begins. 7
Gel forming compositions as described above which comprise a Water soluble salt of alginic acid and a calcium salt Will form a gel upon the addition of water over a Wide range of both acidic and basic pH values. Where the composition for preparing the desired beauty masque is normally alkaline, the gel retarding agent which is commonly used is a soluble phosphate salt such as trisodium phosphate and tetrasodium pyrophosphate. When'such phosphate salts are used as gel retarding agents, the calcium salt present in the composition should be less soluble in water than the phosphate salt. Calcium sulfate is an inexpensive material with the requisite solubility properties and accordingly is the preferred source of calcium ions in alkaline gel forming vehicles containing phosphate salts as gel retarding agents. Upon the addition of such a composition to water, the calcium ions initially formed are removed as a precipitate of calcium phosphate. When the phosphate ions are exhausted, the calcium ions which are formed thereafter are then available for reaction with the alginate salt to form calcium alginate, thereby initiating the gel formation. The elapsed time before gelation is, accordingly, a function of the amount of the phosphate salt present. It is apparent, of course, that the calcium salt should bo-present in a stoichiometric excess con"- pared to the amount of the phosphate salt to insure the availability of'free calcium ions for gel formation.
, Where it is desirableto' utilize a gel forming vehicle having an acidic pH a gel retarding system differing from that described above must be employed. The composition should then contain a compound capable of hydrolyzing slowly to form an acid and the calcium'salt' selected should be a salt which is insoluble in neutral or alkaline media but is slightlysoluble in acid media. Useful com- The gel forming compositions for use in the formation of beauty masques may normally contain as much as three parts by weight of filler per part of the mixture of the alginic acid salt and the calcium salt. In the compositions' of our invention such large amounts of solid filler may be omitted and effective compositions can be prepared Without any solid filler being present.
In preparing the compositions of this invention, between about 05 and about 3 parts by weight of inert liquid are used for each part by Weight of the mixture of the alginic acid salt, the calcium salt and the gel retarding agent.
The compositions of our invention comprising an inert liquid and a gel forming vehicle as described above are generally satisfactory for use, but may be rendered more elegant by the incorporation of an agent designed to stabilize the composition against physical separation of the ingredients. Such stabilization is eifected by blending the inert liquid with such materials as hydroxystearic acid; hydrogenated castor oil, the aluminum, zinc ormagnesium stearates or oleates; the amides of fatty acids, such as stearic, palmitic, lauric and hydroxystearic acids; high molecular Weight hydrocarbons such as polyethylene, polypropylene, the microcrystalline waxes; and bentonite and its derivatives. The inert liquid is heated with the stabilization agent until it is uniformly incorporated therein. Generally, about 0.25 to 5 percent by weight of the stabilization agent based upon the total weight of the composition of our invention is used. We have found that hydroxystearic acid is generally preferred.
Our novel compositions are ideal for the application of various cosmetic and medicinal treating agents to the skin.
to react with and dissolve dead proteinaceous' material pounds which hydrolyze to'yield acids are glucono delta 1 lactone,; galacto'delta-lactone, butyro delta lactone, valero delta lactone, glutaric anhydride, and the like. Calcium salts having the above described solubility properties are calcium ,citrate, tricalciurn phosphate, dicalciurn phos- Upon the addition to' Water of a soluble but alkali insoluble calcium salt and a compound capable of slowly hydrolyzing to form an acid, there will be no free calcium ions initially present for gel formation. As the hydrolyzable compound slowly forms acid, the pH I of the suspension slowly changes to the acid side of pH-7,
thereby resulting in a slow liberation of free calcium ions to. initiate gel formation.
The gel forming composition may, if desired, contain composition with such materials as talc, bentonite, silica and starch being useful. ,In basic rsysteins, magnesium carbonate, calcium carbonate and zincoxide arealso usefulfiillers,-with zinc oxidebeingparticularly effective.

Our novel compositions may range in consistency from a liquidto a thick'pa'ste. Liquid compositions are conveniently packaged in various glass or plastic containers from which the contents may be readily dispensed prior to use. Pasty compositions may bereadily packaged in collapsible thin metal tubes of the type used to package toothpaste, a package insuring easy dispensing of the con- In use,;the. composition is mixed with between 2 and 4 times'its weight of water to form a uniform suspension.

' has been found that the gel structure obtained by use of our compositions has a high tensile strength and does not exhibit any tendency toward cracking or lifting from the skin. Moreover, no dry powdery'material is formed around the edges of thefilm, and the entire film may easily be removed fromthe skin by peeling off as a single sheet or in several sections. a V
